Overview
The LTC2634CMSE-LMX12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 125°C temperature range, and low noise of 0.75mVP-P. Communication occurs via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Power-on reset defaults to mid-scale in external reference mode.
Feature Summary
- Quad 12-bit DACs with integrated 10ppm/°C precision reference
- Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
- SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz
- Power-on reset to mid-scale in external reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific ordering suffix #TRPBF indicates a tape and reel configuration containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the LMX12 code aligns with the required 2.5V full-scale output and mid-scale power-on reset behavior for external reference applications.
Selection Notes
Select this part when a quad 12-bit DAC with a 2.5V internal full-scale range is required in a compact MSOP package. The LMX12 variant is appropriate for systems needing mid-scale initialization during power-up while utilizing an external reference source. Verify that the 2.7V to 5.5V supply range meets system voltage constraints.
Part Context
This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The CMSE prefix denotes the Commercial temperature grade (0°C to 70°C) and the 10-lead MSOP package. The LMX12 suffix specifies the 2.5V full-scale voltage and mid-scale reset in external reference mode.
Replacement Considerations
Direct replacements within the same family include LTC2634CMSE-LMI12#TRPBF for internal reference mid-scale reset or LTC2634CMSE-LZ12#TRPBF for zero-scale reset. For automotive applications, consider the H-grade variants such as LTC2634HSE-LMX12#WTRPBF if extended temperature ranges are needed.
